Final answer:
Cardiac muscle does not have a high regenerative capacity. Dead cardiac muscle cells are replaced by scar tissue, which cannot contract. Some minor regeneration may occur due to stem cells found in the blood.
Step-by-step explanation:
No, cardiac muscle does not have a high regenerative capacity.
When cardiac muscle cells die, they are usually replaced by scar tissue, which does not have the ability to contract. As scar tissue accumulates, the heart loses its ability to pump effectively.
However, some minor regeneration may occur in cardiac tissue due to stem cells found in the blood that occasionally enter the heart.
